Generally, virtual systems have several user space instances virtualized at the operating system level. Many devices today, such as smartphones, tablets, and cloud computing systems, are virtualized to include several user space instances, which allows for greater granularity and control over the software on a device. Although a typical operating system includes one kernel space and one user space, a virtualized system may include one kernel space and several user space instances (sometimes called “containers”). Virtualized systems allow each container to be isolated, however, some communication may still be required between containers.
